  • Patent number: 7553096
    Abstract: Selectively printing full and fractional sized images with a donor ribbon. A first print order and indicia are printed while the donor ribbon is advanced through the printer. Printing is performed using donor material on a first fraction of the patch set when the print order requests a fractional sized image, or on a full patch when the print order requests a full sized image. When a second print order requests a fractional sized image, a determination is made whether the second fraction of the patch set is available for printing. An image based upon the second print order is printed using donor material from the second fraction of the patch set when it is available, or the donor ribbon is advanced to the next patch set when it is determined that the second fraction of the patch set is not available.

  • Patent number: 4738555
    Abstract: Method and apparatus for the thermal transfer printing upon a record medium utilizing a print ribbon so as to form a protective transparent layer over a printed area upon a record medium. The thermal transfer print film includes plural colored ink regions separated by transparent ink regions. The method and apparatus of the present invention thus provide for the initial printing via thermal transfer of the colored ink regions onto an area of the record medium. Subsequent alignment of a region of the transparent ink with the printed area on the record medium and selective operation of thermal print heads thus thermally transfers portions of the thermal transparent ink to the previously colored ink printed area to provide a transparent ink layer over the printed information upon the record medium thereby protecting the same.

  • Patent number: 4707155
    Abstract: An apparatus for supplying a newly re-coated continuous ribbon to a moving printhead carrier in a printer. The present invention is particularly adaptable for use in thermal printers having multicolored ribbons. The apparatus comprises a cartridge housing which is mounted on the printer frame, and which contains the ribbons. The newly re-coated ribbons exit the cartridge housing, become coupled to the moving printhead carrier, and then reenter the cartridge housing as used ribbon. The used ribbon passes a re-coating station where it is re-inked through contact with a donor ribbon and heated pressure rollers to become newly re-coated ribbon. A lift arm on the printhead carrier selects the desired colored ribbon which has been newly re-coated for printing.

  • Patent number: 4641147
    Abstract: The present invention is equipped with a plurality of print buffers for inputting print data into a thermal head, wherein such print data are selectively fed to simply change the current on-time for energizing the heating elements of the thermal head relative to specific information out of the entire information to be printed, so that the specific information is printed emphatically in a particular color to become conspicuous, and simultaneously the contour of each specific character is edged in a basic color to be distinctly legible. Such edged print is attained by utilizing the gradient of the temperature distribution induced in the heating elements by the current on-time control system, hence eliminating the necessity of any edging print data to consequently simplify the control.
